Merge branch 'core-mm-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull unified TLB flushing from Ingo Molnar: "This contains the generic mmu_gather feature from Peter Zijlstra, which is an all-arch unification of TLB flushing APIs, via the following (broad) steps: - enhance the <asm-generic/tlb.h> APIs to cover more arch details - convert most TLB flushing arch implementations to the generic <asm-generic/tlb.h> APIs. - remove leftovers of per arch implementations After this series every single architecture makes use of the unified TLB flushing APIs" * 'core-mm-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: mm/resource: Use resource_overlaps() to simplify region_intersects() ia64/tlb: Eradicate tlb_migrate_finish() callback asm-generic/tlb: Remove tlb_table_flush() asm-generic/tlb: Remove tlb_flush_mmu_free() asm-generic/tlb: Remove CONFIG_HAVE_GENERIC_MMU_GATHER asm-generic/tlb: Remove arch_tlb*_mmu() s390/tlb: Convert to generic mmu_gather asm-generic/tlb: Introduce CONFIG_HAVE_MMU_GATHER_NO_GATHER=y arch/tlb: Clean up simple architectures um/tlb: Convert to generic mmu_gather sh/tlb: Convert SH to generic mmu_gather ia64/tlb: Convert to generic mmu_gather arm/tlb: Convert to generic mmu_gather asm-generic/tlb, arch: Invert CONFIG_HAVE_RCU_TABLE_INVALIDATE asm-generic/tlb, ia64: Conditionally provide tlb_migrate_finish() asm-generic/tlb: Provide generic tlb_flush() based on flush_tlb_mm() asm-generic/tlb, arch: Provide generic tlb_flush() based on flush_tlb_range() asm-generic/tlb, arch: Provide generic VIPT cache flush asm-generic/tlb, arch: Provide CONFIG_HAVE_MMU_GATHER_PAGE_SIZE asm-generic/tlb: Provide a comment
